ROTARY APPARATUS FOR TREATING MATERIALS.

Application filed July 15, 1910, Serial No. 572,132.

To all whom it may concern:

Be it known that I, JO N W. Ho NsEY,

a citizen of the United States, residing at Summit, Union county, NewJersey, have invented a new and useful Improvement-in Rotary Apparatusfor Treating Materials, of which the following is aspecificatiom'reference being had to the accompanying drawings, in whichFigure 1 is a-seotion in perspective of a rotary cylinder equipped withmy improvement; Figs. 2 and 3 are similar sections tary apparatus. 1

' My invention is of particular value in.

the treatment of materials which tend to become sticky during thetreatment; or must be introduced into the apparatus in asticky orcohesive condition.

I shall herein show and describe my apparatus in the forms which I havefound to be preferable for actual use; but it will be understood thatmany changes may be made, and that the forms here illustrated anddescribed constitute merely preferred embodi-v ments of my invention.

Referring to the drawings, 1 is a section of a rotating cylinderequipped with my apparatus. At various points .inthe cylinder areattached the eye-bolts 3 which are se cured by suitable lock-nuts l, andthrough the eyes of which pass the hinge pins 5 on which are supportedthe hinges 6 of the movable buckets or cradles 7. These cradles consisteach of'two side pieces 8 andfa series of cups or shelves 9 arranged inladder fashion from the outer ends of the side pieces to near the hingeends, and as the cylinder rotates they serve to carry the materialupward, and, after having passed a certain position, the Weight of theunbal Specification of Illetters Patent.

anced outer ends of the cradles 7 is sufficient to cause them to falldownward. It is desirable to stop this downward movement abruptly so asto dislodge any material that may have adhered to the cradles. Thisabrupt stop may be provided for in various ways. o

In Fig. 1 I show a cylinder 2 against which each cradle, as it iselevated in the rotation of the cylinder and falls downward, comes torest with a sudden jar, thereby dislodging any adhering material. Uponfurther continuance of the, rotation the cradles fall back against theouter cylinder as before. The inside edges 10 of the cups 9, as shownin. Fig. 1, and the outer edges 11 of the cups 9 and of the side pieces8, as shown in detail in Figs. 6 and 7 are preferably sharpenedso thatwhen they fall against the inner cylinder 2 (in Fig. 1), or back againstthe sides of the cylinder .1, they serve to cut away any materialadhering to either the cylinder -or' to, the flue, which might otherwisebuild up and render the cradles inoperative. The motion of the cradlesis accompanied by "a blow of consid erablemagnitude as they fall intoeither position, which assists them in removing the I adhering material,and in cases'where' the inner cylinder 2 is stationary, as respects thecylinder 1, the edges 10 act as scrapers to efl'ectively remove all ofthe material adhering to the top of the inner cylinder 2. y In. order toincrease the force of the blow 7,

produced bythe falling bucket,'I may if I I so desire, weight the outerend of the cradle 7 as shown more particularly by' the weighted portion7( in Figs. 5'and 6. The inner cylinder may be used to convey heatinggases if desired. The blows produced b y the cradles falling against thesides of the cylinder, in conjunction with the cutting action of thesharpened edgesiof the cradles, I have found to be amply sufiicient inall cases" to dislodge anymaterial adhering to the inside of I thecylinder. When the material has become partly dried and agglomeratedinto distinct masses of some degree of solidity, the cradles alsolser'veto 'break,'- crush and grmd up this agglomerated material into smallerparticles, so that the resulting product is more uniform both asrespects the size of the par ticles and the completeness of thetreatment of each particle.

The cup or shelves 9 may be riveted or otherwise attached to the sidepieces, as shown in some of the figures, or may be cast integral withthem as indicated in Figs. 6 and 7.

In Fig. 2 I show a modified form of stop consisting of stirrups 12 whichare hinged upon the pins 5 so as to fold down against the cradles whenin their lower position, as shown in the figure. In the upper portion ofthe cylinder the cradles fall forward as in the arrangement of Fig. 1and are caught and abruptly stopped by the stirrups 12. In Fig.2 I alsoshow a second set of cradles which are staggered in position as respectsthe first set, but in all other respects are 7 similar. The objects tobe attained by staggering the cradles, are, first, to present a deviouspath for any fluid which might tend to flow endwise through the lowerportion of the cylinder, and, second, to cause the operation ofadjoining sets of cradles to take place successively, and thereby thematerial contained in and adhering to the cups of the cradles is causedto shower down and to be distributed more uniformly, and the formationof voids or blank V-shaped spaces through which a gas traversing thecylinder might pass without interacting effectively with the materialcontained in the cradles, is to a large extent obviated.

In Fig. 3 I show another modification in which, instead of the movablestirrups 12 I have substituted the rigid stirrups 13, through theextremities of which the bars 14 pass. These rigid stirrups 1,3 arepinned to the rings 15 by the pins 16, which also serve as hinge pinsfor the cradles themselves. The check rings 15are provided for thepurposes described in my companion application filed July 15, 1910,Serial No. 572131, and where it is desired to use both cradles andbuckets in the same cylinder the buckets may be attached to one side ofthe check ring 15 as described in my companion application, and thecradles to the other side. I may also construct my check rings so thateither buckets or cradles may be used in connection with them, asdesired, in view of the consistency of the material to be treated in thecylinder.

In the arrangements illustrated in Figs. 1' and 2, no fixed checkrings'are shown and the side pieces 8, when made broad as shown in thosefigures, act as check rings.

' In Fig. 4: I show a further modification in which, within the cylinder1, there is provided a loose rotary cage 17 consisting of the annularside pieces 18 and the buckets 19 arranged in ladder fashion betweenthem and attached to them in any suitable man ner. Upon the cylinder 1at suitable intervals here shown as 180 apart, I place the projections20. If the cylinder be rotated in the direction of the arrow, the cage17 will roll up the projections 20 on their inclined sides 21, and willthen fall against the side of the cylinder, thereby producing a blow ofsufficient violence to dislodge any material adhering to the cage 17 orto the cylinder 1. This action is in all respects analogous to thatproduced by the cradles 7, and the outside edges of the buckets 19 andof the cage 17 may be sharpened so as to assist in cutting away theadhering material in a similar fashion. The cage may eX- tend the wholelength of the cylinder, or for only a portion thereof, and instead ofone long cage there may be a series of shorter ones; and, if itisdesired to provide cages for only a portion or certain portions of thecylinder, the cages may conveniently be held in place by making themslightly larger in diameter than the inner diameter of the fixed checkrings 15, if such are provided, as shown in Figs. 1 and 5.

All such modifications are obviously within the scope of my invention.

The. speed of rotation of the cylinder should be governed by thecharacter of the material-being treated, and partly by the intensity ofthe blow or jar which it is desired to produce when the movable bucketsor cradles fall upon the stops, for, by regulating the speed of rotationI have found that I can regulate the intensity of the blow to a nicety.g

What I claim is:

1. In apparatus for treating materials, a rotating chamber, shelvesrotating with said chamber and adapted to lift and drop the materialunder treatment, supports for said shelves, and means for causing suchshelves to move with relation to said cylinder and means for abruptlystopping such motion.

2. In apparatus for treating materials, a rotating chamber havingtherein a series of pivotally mounted cradles and means for arrestingthe movement of said cradles during the rotation of the cylinder.

5.
